<![CDATA[Geometry of space becomes a more difficult course compared with the basic geometry. Considerable evidence indicates the level of difficulty. In the geometry of space, students still have to transform three-dimensional objects into two-dimensional image field. This is related to spatial ability students. By combining the usefulness of mathematics and the development of science and technology it developed a mathematical model of teaching based on computer technology. The use of Cabri 3D in teaching space geometry was meant for the students to make educated guesses / conjectures, test conjectures, construct and make generalizations generally. The hope with the help of computers, the constraints and difficulties that exist can be eliminated little by little. The problems are going to be resolved through this study were 1). Are there differences in the ability of understanding the concept of school geometry student research through teaching strategies and direct instruction assisted Cabri 3D? 2). Are there differences in the ability of generalization through teaching strategies and direct student research Cabri 3D-aided instruction? The subject of this study is the fourth semester students of the school year 2010/2011 State University majoring in mathematics negei Semarang. The results showed 1). There were no differences in the ability of understanding the concept of school geometry student research through teaching strategies and direct instruction assisted Cabri 3D. 2). There are differences in the ability of generalization through teaching strategies student-assisted research and direct instruction Cabri 3D.]]>

<![CDATA[Kemampuan berpikir kritis dan kreatif mahasiswa masih lemah. Hal ini ditemukan pada mahasiswa yang mengambil mata kuliah Geometri Ruang yaitu dalam membuktikan soal-soal pembuktian (problem to proof). Mahasiswa masih menyelesaikan secara algoritmik atau prosedural sehingga diperlukan pengembangan perangkat pembelajaran Geometri Ruang berbasis kompetensi dan konservasi dengan model Proving Theorem. Dalam penelitian ini perangkat perkuliahan yang dikembangkan yaitu Silabus, Satuan Acara Perkuliahan (SAP), Kontrak Perkuliahan, Media Pembelajaran, Bahan Ajar, Tes UTS dan UAS serta Angket Karakter Konservasi telah dilaksanakan dengan baik dengan kriteria (1) validasi perangkat pembelajaran mata kuliah Geometri ruang berbasis kompetensi dan konservasi dengan model proving theorem berkategori baik dan layak digunakan dan (2) keterlaksanaan RPP pada pembelajaran yang dikembangkan secara keseluruhan berkategori baik.Critical and creative thinking abilities of students still weak. It is found in students who take Space Geometry subjects that is in solving problems to to prove. Students still finish in algorithmic or procedural so that the required the development of Space Geometry learning tools based on competency and conservation with Proving Theorem models. This is a research development which refers to the 4-D models that have been modified for the Space Geometry learning tools, second semester academic year 2014/2015. Instruments used include validation sheet, learning tools and character assessment questionnaire. In this research, the learning tools are developed, namely Syllabus, Lesson Plan, Lecture Contract, Learning Media, Teaching Material, Tests, and Character Conservation Questionnaire had been properly implemented with the criteria (1) validation of Space Geometry learning tools based on competency and conservation with Proving Theorem models categorized good and feasible to use, and (2) the implementation of Lesson Plan on learning categorized good overall. ]]>

<![CDATA[Berbagai model pengajaran masuk ke Indonesia dengan berbagai karakteristik yang belum tentu cocok dengan kondisi Indonesia. Ketidakcocokan tersebut dapat ditinjau dari berbagai faktor, mulai dari latar belakang siswa, budaya, kondisi geografis, guru, kurikulum dan sebagainya ketika dibandingkan dengan negara asalnya, yakni Belanda dengan Realistic Mathematics Education (RME) dan Amerika untuk Contextual Teaching and Laerning (CTL). Indonesia dengan segala keberagamannya termasuk kekayaan budayanya merupkan potensi yang tak ternilai untuk dieksplorasi menjadi sumber pengajaran matematika dengan penciri yang khas. Artikel ini memberikan gambaran awal dalam menciptakan suatu model pembelajaran matematika berbasis budaya yang ada di nusantara dengan nama Matematika Nusantara. Uji coba model ini telah dilaksanakan pada pelatihan untuk guru-guru matematika di kabupaten Serang-Banten. Respon yang positif dan optimis dari peserta menjadikan model Matematika Nusantara mantap dapat diimplementasikan di Indonesia dengan fleksibilitas yang tinggi sesuai dengan karakteristik budaya di masing-masing daerah.
Kata kunci: matematika nusantara; matematika berbasis budaya
ABSTRACT
Various learning models came to Indonesia with various characteristics that may not necessarily match with the conditions of Indonesia. That incompatibility can be observed from many factors, such as student background, culture, geographical conditions, teachers, curriculum, and so on, when they are compared to their origin country, Netherlands for the Realistic Mathematics Education (RME) and America for the Contextual Teaching and Learning (CTL). Indonesia with all its cultural diversity is the most valuable potential to be explored as an unique mathematical learning material. This article provides the first description in creating an Indonesian cultural-based mathematics learning model named Matematika Nusantara. This model has been tested and implemented in mathematics teacher training in Kabupaten Serang, Banten. The positive and optimistic response from the participants shows that Matematika Nusantara model can be steady implemented in Indonesia with high flexibility for any curtural characteristics in each region.
Keywords: matematika nusantara, curtural-based mathematics]]>

<![CDATA[Penelitian ini bertujuan mengetahui jenis kesalahan dan penyebabnya pada siswa kelas X SMA Negeri 1 Kendal Tahun Pelajaran 2011/2012 dalam menyelesaikan soal materi jarak pada bangun ruang dengan menggunakan prosedur Newman. Penelitian ini merupakan penelitian kualitatif. Pengumpulan data dilakukan dengan metode tes dan metode wawancara. Subjek penelitian diambil 6 orang dari 33 siswa kelas X-5, masing-masing terdiri atas 2 siswa dari kelompok atas, 2 siswa dari kelompok sedang dan 2 siswa dari kelompok bawah yang selanjutnya dilakukan wawancara terkait kesalahan yang dilakukan pada lembar pekerjaannya. Uji keabsahan data dilakukan dengan teknik triangulasi. Berdasarkan analisis hasil penelitian diketahui bahwa dalam menyelesaikan soal dengan prosedur Newman tidak ada satupun subjek penelitian yang melakukan jenis kesalahan membaca. Jenis kesalahan memahami masalah dilakukan oleh 4 subjek penelitian. Penyebabnya adalah karena ilustrasi yang salah. Jenis kesalahan transformasi tidak ada yang melakukannya. Jenis kesalahan kemampuan memproses dan penulisan jawaban, dilakukan oleh tiga subjek penelitian. Penyebabnya adalah karena salah dalam memanipulasi aljabar dan kurang cermat dalam menulis.]]>
